Deputies arrested a man Thursday on suspicion of stealing from parked cars at a cemetery while mourners visited grave sites.

Tommy James Lopez, 34, of San Gabriel, was booked on suspicion of petty theft from a vehicle and was being investigated in connection with at least four similar thefts at the same location — Forest Lawn Memorial Park and Mortuary, 21300 East Via Verde Street in an unincorporated county area near Covina, Los Angeles County sheriff’s officials said.

A woman was visiting a grave at the cemetery about 10:20 a.m. when someone spotted Lopez stealing items from her unlocked car, Sgt. Steve Perez said.

The witness informed a security guard, who followed Lopez to the exit and flagged down a nearby Highway Patrol Officer, who took Lopez into custody, Perez said.

Perez was found in possession of several items believed to have been taken several similar break-ins at Forest Lawn reported over the past two months, Estrada said. The thefts primarily targeted women visiting the cemetery who left their cars unlocked.

Sgt. Mario Estrada reminded residents to keep valuables out of view in their cars to avoid creating temptations for opportunistic thieves, especially during the holiday season when auto burglaries tend to increase.

According to county booking records, Lopez was being held in lieu of $52,000 bail and was due for arraignment Tuesday in West Covina Superior Court.
